项目摘要
Single- and double- ayer graphene nanoribbons (GNRs) with widths of around 10 nm were synthesized directly onto an insulating substrate by solid-phase graphitization using a gallium vapor catalyst and carbon templates made of amyloid fibrils. Subsequent investigation revealed that the crystallinity, conductance and carrier mobility were all improved by increasing the temperature of synthesis. The carrier mobility of GNRs synthesized at 1050 degree C was 0.83 cm2/Vs, which is lower than that of mechanically exfoliated graphene. This is considered to be most likely due to electron scattering by the defects and edges of the GNRs.
通过固相石墨化,使用镓蒸气催化剂和由淀粉样蛋白原纤维制成的碳模板,直接在绝缘基底上合成具有约10 nm宽度的单层和艾耶尔石墨烯纳米带(GNR)。随后的研究表明,随着合成温度的升高,薄膜的结晶度、电导率和载流子迁移率都得到了提高。在1050 ℃下合成的GNRs的载流子迁移率为0.83 cm 2/Vs,这低于机械剥离的石墨烯的载流子迁移率。这被认为最有可能是由于GNR的缺陷和边缘的电子散射。
